Pumps adapted to each of your applications

  • Irradiated / Contaminated Liquids

  • Boric acid

  • Hermetic circuit

Canned Motor Pumps – SMR Range


The Rütschi canned motor pumps ensure an absolute sealing for even greater safety and reliability.
Thanks to a simple and robust design, without dynamic sealing, they have a very long life time with a low maintenance rate.
